I have installed Mach4 on my 2012 Shopmaster. It was quite a laborious process, with much trial and error, and error, and error! To save others the trouble, I'm posting a link to a document I wrote detailing the steps needed to run Mach4. By the way, I believe its a big improvement over Mach3. I also use Fusion 360 processors without a problem on the Shopmaster. The file is too large to upload and so here's a link to access the file.

The usual caveats apply: don't blame me for any errors in the document. If you do find any, do let me know.
